Sing a slow, comfortable scale — glide from your lowest note up to your highest and back down a few times. Hold each note for a second so the detector locks onto it clearly.

Overview

Vocal Range Test. Baritone or tenor, alto or soprano — Vocal Range Test listens through your microphone and tracks your pitch live while you sing. Click Start Listening and sing from your lowest note up to your highest to map your full range, and your Lowest Sung note, Highest Sung note, and a standard classification from bass through soprano appear as you go — a different question from the site's hearing-range tests, which measure what you can hear rather than what you can sing. Watch the decibel meter online update in real time as you test.

Curious where your voice really sits? This free vocal range test listens while you sing two notes, then reports your lowest and highest notes, the span between them and the voice category it fits. It works like a vocal range quiz with no questions, so any singer gets results based on sound rather than a guess.

How the Vocal Range Test Finds Your Lowest Note and Highest Note

The tool reads the pitch coming through your mic, matches each frequency to the nearest piano key and marks the two boundaries. To test your vocal range:

  1. Press record and sing the lowest note you can produce cleanly on an open "ah".
  2. Repeat with the highest note you can hold without forcing.
  3. Read the two note names, the span and the matching voice type.

Microphone, Browser and Headphones Setup

Allow mic access when the browser asks and pick the right input device. Switch off aggressive noise suppression, since it can clip the signal the tool reads. Wear headphones if you play reference tones, so speaker sound doesn't return as feedback. A quiet room matters more than an expensive mic: background noise is the usual reason a reading jumps around.

Why You Hold a Steady Note for a Few Seconds

A tone held for three to six seconds lets the detector ignore the wobble at the start, breath noise and stray harmonics, then settle on what you actually sustain. A quick squeak can register something you could never use in a song, so a long, even tone gives a more reliable result.

Reading Your Comfortable Range in Note Names, Semitones and Octaves

Your result is a comfortable range: what you can sing comfortably and repeat on purpose, not the extremes you hit once. That baseline is what you'll use for real songs. Take a worked example: a bottom of B2 (123.47 Hz) and a top of G4 (392.00). The span in half steps, S, comes from the frequency ratio: Open the live microphone frequency spectrum analyzer in another tab any time you need a quick live reading.

$$S = 12 \times \log_2\left(\frac{f_{\text{high}}}{f_{\text{low}}}\right) = 12 \times \log_2\left(\frac{392.00}{123.47}\right) = 20$$

Divide by 12 to get octaves: \(20 \div 12 = 1.67\).

Formula converting a B2 to G4 vocal range into 20 semitones, with the range highlighted on a C2 to C6 keyboard chart
B2 to G4 spans 20 semitones, or 1.67 octaves.

Scientific Pitch Notation and Middle C

Labels follow scientific pitch notation: a letter plus a number, with each new number starting on C. Middle C is C4, about 261.63 Hz, so B2 sits more than an octave below it and G4 just above it. Every pitch follows \(f = 440 \times 2^{(n-69)/12}\), where n is the MIDI number. That bit of music theory is how a tool names raw frequency.

Counting Semitones and Octaves on the Keyboard Chart

The keyboard chart highlights everything between your two boundaries. Each step to the next black or white key is one semitone, and 12 steps make an octave. B2 to G4 covers 20 steps, a typical untrained span; two full octaves is a common goal after a year of training.

Your Vocal Range vs. Range Extension

Your vocal range is the set of pitches you can produce with a clear, controlled tone. Anything forced out with strain belongs to your range extension and inflates the number without helping a single song. Stop at the first tightness or pain: pushing the edges tires the vocal cords, while healthy technique widens your natural singing range over months.

Picking an Audition Key from My Singing Range Result

I have a community choir audition in nine days, and the solo I've chosen runs from A3 to E5 in its printed key. The question is simple: do I sing it as written, or ask the accompanist to drop it, and by how much? I don't want to guess, so I run the test before rehearsing. The free room mode calculator runs entirely in your browser — nothing you enter is ever sent anywhere.

Cold, I hold an "ah" on my bottom note for five seconds. The readout settles on 172.6 Hz, labelled F3, which is 20 cents flat of F3's 174.61 Hz. My top held note reads 519.8 Hz, labelled C5. I also squeak out a brief F#5, but it lasts under a second, so I ignore it: that's range extension, not something I'd put in front of a panel.

So my comfortable vocal range is F3 to C5, 19 semitones. The song spans A3 to E5, also 19 semitones, but sits 4 semitones higher. Transposing down a major third would put it at exactly F3 to C5, with zero margin at either end. That sits inside the standard alto range of F3 to F5, but only in its lower half.

Zero margin worries me. Nerves usually cost me a semitone or two at the top, so I warm up for ten minutes and rerun:

RunBottomTopSpanHeadroom if transposed down 3
ColdF3 (172.6 Hz)C5 (519.8 Hz)19top 1 semitone over
Warmed upF3 (172.6 Hz)D5 (584.1 Hz)211 semitone spare at each end

The warmed-up top reads 9.5 cents flat of D5's 587.33 Hz, and I check the span by hand: \(12 \times \log_2(584.1 \div 172.6) = 21.1\), so the label of 21 holds up. My decision is to ask for the song down 3 semitones (F#3 to C#5), not 4, which keeps it brighter and still leaves a semitone of headroom, provided I warm up first.

One thing I'd watch: the bottom reading is 20 cents flat. Had it drifted past 50 cents, the tool would have labelled it E3 and handed me a semitone I don't really own. When a reading sits near a boundary, hold the note again rather than trusting one label. The input that matters most here is the warmed-up top, not the bottom; it decides the key.

Which Voice Type Matches Your Result

Compare your two boundaries with the six standard choir categories. Ranges overlap, so the best fit is the type that shares the most of your singing range. The last column counts the shared semitones for the B2 to G4 example.

CategoryTypical rangeShared with B2–G4
SopranoC4–C67
Mezzo-sopranoA3–A510
AltoF3–F514
TenorC3–C519
BaritoneA2–A420
BassE2–E417

Choir parts are written around these ranges so they stack into four-part harmony.

The example fits baritone best, with its neighbour a close second.

Soprano, Mezzo-Soprano and Alto Voice Types

Higher voices usually fall into these three. Sopranos sit highest and carry melodies, mezzos share much of that territory with a darker colour, and the lowest of the three anchors the lower treble line. The rarest category is the countertenor, a male singer who reaches the same territory with a light tone.

Tenor, Baritone and Bass Ranges

Lower voices split the same way: tenors ride the top of the male range, baritones sit in the middle where most untrained men land, and basses supply the foundation the rest of the music rests on. When a result straddles two neighbouring types, as B2 to G4 does, tone quality settles it.

Tessitura, Timbre and Famous Singers

Range is only part of classification. Tessitura, where your voice feels most at home, and timbre, its colour, both weigh in, which is why a teacher assesses them in person. Comparing your boundaries with famous singers is fun, but two singers can share an identical span and still differ in type. Treat the label as a starting point for singing, whether you're a working musician or a karaoke regular.

Tips to Find Your Vocal Range Accurately and Track It

An online vocal range test is accurate when the input is clean and your effort stays consistent between attempts. Free habits that make the reading worth trusting:

  • Do five minutes of warm-ups, such as lip trills and slides, first.
  • Use good breath support and a moderate volume; shouting adds noise, not range.
  • Use your comfortable top note to pick a key: if a song peaks above it, transpose down to fit your repertoire.
  • Retest every few weeks to track your progress after practice or singing lessons.

Frequently Asked Questions

How does a vocal range test work?
It turns your lowest and highest notes into a range. With a microphone test you hold each note for a few seconds while the tool detects its pitch; here you pick the two notes and the calculator converts them into note names, a span in semitones and octaves, and the closest voice type.
What's the difference between vocal range and voice type?
Your vocal range is the distance between the lowest and highest notes you can sing. Your voice type (bass, baritone, tenor, alto, mezzo-soprano or soprano) describes where that range sits and where your voice is most comfortable, so two singers with the same span can still be different types.
What are the six voice types and their ranges?
Typical ranges are bass E2–E4, baritone A2–A4, tenor C3–C5, alto F3–F5, mezzo-soprano A3–A5 and soprano C4–C6. They overlap, so the tool picks the best overall fit rather than using a hard cut-off.
Should I count notes I can only hit for a moment?
No. Use notes you can sustain steadily for about two seconds or more. Brief squeaks or strained low growls belong to your range extension and make the result less useful for choosing songs.
How accurate is an online vocal range test?
It's a reliable starting point when you sing steady notes in a quiet room. Full voice classification also weighs tessitura and timbre, which a voice teacher judges in person.
Can my vocal range change?
Yes. With warm-ups, breath support and regular technique work most people gain a few semitones over time. Retest every few weeks to track your progress.
Is it safe to test my highest and lowest notes?
Yes, as long as you stay comfortable. Stop as soon as you feel strain or pain, and don't push the extremes over and over.
